Bicep Curl

Bicep Curl

Using a weight, do a normal bicep curl. The resistance of the water will make you work harder in both directions, especially if you use a special pool weight like the  Aqualogix bells. "The fins allow you to isolate different muscle groups by adjusting the water resistance," says Chris Kost, who has 20 years of aquatics experience working with pro athletes like baseballer Joe Mauer.Tip: Be careful to keep the full range of motion under the water.
